I just realized, the key is that you can put a weight on the opposite side of the scale. So if I want to weigh out one pound of green beans, I put the 1-1/2 on one side, the 1/2 on the other side, and add green beans until it balances. Very clever.

I was wondering if I had to specify a balance scale as opposed to a spring scale.

Very Clever...

Notice that if you changed it to whole numbers (1 to 40 pounds) the weights would be 1, 3, 9, 27 (3^0, 3^1, etc.)

I was thinking about this last night while I was sleeping.

What does the following cyclic pattern of numbers represent?

0
1
3
2
6
7
5
4
0

Starting with the top number, it's how many steps forward I take, followed by how many backward, how many forward again, backward...etc and so on.

HungLikeJesus · 01-13-2012, 11:44 AM

So you always end up back where you started!

infinite monkey · 01-13-2012, 11:48 AM

I KNEW this looked familiar.

Clodfobble · 01-13-2012, 02:47 PM

I want there to be a reason that the first letters of the number names are in a pattern as well (z, o, t, t, s, s, f, f, z)... But it's not reverse alphabetical order, because 3/2 and 5/4 would be out of place.

I dream in binary.

You made a small error (you skipped 2).
It should be:

0 000
1 001
3 011
2 010
6 110
7 111
5 101
4 100
0 000
... ...

The answer is that each number only changes a single digit from the previous number.

And for bonus points, what is this pattern called, and what is it used for?

There's no 8 in binary?
